What I'm looking for

I’m looking for a team where I can build scalable MERN and .NET applications, improve data integrity and reporting quality, and grow through continuous engineering improvement on high-performance projects.

I’m a Full Stack Developer & Data Analyst focused on building scalable, high-performance software solutions. I specialize in the .NET ecosystem (C#) for enterprise architecture and the MERN stack (React, Node.js) for modern web applications, with a strong ability to translate business requirements into efficient code.

In my freelance work (2023–Present), I lead the end-to-end lifecycle of digital products—from brand identity and UI/UX design to full stack implementation. I focus on scalable e-commerce ecosystems and performance-oriented web applications using modern architectures (MERN & .NET) to solve complex business challenges.

I also bring analytical and quality strengths from my role as a Technical Data Analyst & QA (2024–2025), ensuring technical data integrity and reporting accuracy for environmental monitoring deliverables. Earlier, as an IT Support Specialist (2020–Present), I handled diagnostics, repairs, OS and driver updates, basic networking, and data backup/recovery—strengthening my practical engineering mindset.
